CEDRONELLA

 and Ailanthus. Cedrela on

A. Lfts. 10-25. 



B. Lvs. quite glabrous. 



c. Margin of Ivs. more or less serrate: panicles very long, 



pendulous: seeds winged above. 



sinensis, Juss. (Tobna sinensis, Roem. Aildnthus 

 flavescens, Carr.). Tree to 50 ft.: Ivs. long - petioled, 

 10-20 in. long; Ifts. 10-22, oblong or oblong-lanceolate, 

 acuminate, slightly and re- 

 motely serrate, light green 

 beneath, 4-8 in. long: fls. 

 white, in very long, pendulous 

 panicles; ovary glabrous; 5 

 subulate staminodes alter- 

 nating with the stamens: fr. 

 oblong or obovate, about 1

 1. Ornamental tree, with 

 large feathery foliage; very 

 valuable for avenues; similar 

 to ailanthus, and nearly of the 

 same hardiness, but of more 

 regular and dense growth, 

 and without the disagreeable 

 odor when flowering. Ailan- 

 thus can be easily distin- 

 guished by the few coarse 

 teeth near the base of the 

 Ifts., each bearing a large 

 gland beneath (Fig. 849). 



serrata, Royle (Tobna serrdta, Roem.). Tree, to 70 

 ft.: Ivs. usually odd-pinnate, 15-20 in. long; Ifts. 15-25, 

 ovate-lanceolate or ovate-acuminate, irregularly ser- 

 rate, glaucous beneath: panicles longer than the Ivs., 

 pendulous; fls. fragrant, often 6-merous; ovary glabrous. 

 Himalayas, to 8,000 ft. altitude. Royle, 111. 25. Col- 

 lett, Flor. Siml. 82. This is probably the hardiest of 

 the tropical species. Sometimes united with C. Toona. 



cc. Margin of Ivs. entire: 



panicles shorter than 



the Ivs. 



Toona, Roxbg. (Toona 

 ciliata, Roem.). Tree, to 

 70 ft., nearly evergreen: 

 Ivs. abruptly pinnate; 

 Ifts. 10-20, usually op- 

 posite, lanceolate or 

 ovate-lanceolate, some- 

 times undulate, 3-6 in. 

 long: fls. white, honey- 

 scented, 5-merous; ovary 

 hairy; seeds winged at 

 both ends. Himalayas.

 INDIAN CEDAR. Tree, to 

 100 ft.: Ivs. 10-20 in. 

 long; Ifts. 12-20, ovate- 

 lanceolate, acuminate, 

 entire, bright green on 

 both sides, 4-6 in. long: 

 panicles shorter than the 

 Ivs.: fr. oblong, 1^ in. 

 long; seeds winged be- 

 low. W. Indies. The 

 cedar wood comes mostly 

 from this species. Wood 

 brown, fragrant, the 

 source of the cigar-box 

 wood of commerce. It 

 is a very durable wood,

and is much prized in the W. Indies in the manufacture 

 of cabinets, furniture, canoes, and other articles. In the 

 W. Indies known as "cedar." 



BB. Lvs. densely pubescent beneath. 



fissilis, Veil. Tree: Ivs. 10-15 in. long, abruptly pin- 

 nate; Ifts. 18-24, opposite, nearly sessile, oblong- 

 lanceolate, acuminate: panicles pubescent, longer than 

 the Ivs.; calyx pubescent outside; petals fulvous tomen- 

 tose; ovary glabrous. Brazil, Paraguay. St. Hilaire, 

 Fl. Brazil. 2: 101. According to Franceschi it does 

 better at Santa Barbara than any other species of this 

 genus. 



AA. Lfts. 6-10, finely ciliate. 



Dugesii, Wats. Tree: Ivs. 10-15 in. long; Ifts. cuneate, 

 ovate-lanceolate, long and slender acuminate, nearly 

 entire, shining above, pale green and glabrous or nearly 

 so beneath, 46 in. long: panicles rather compact, much 

 shorter than the Ivs. Mex. ALFRED REHDER. 



CEDRONELLA (a little cedar, from the odor of C. 

 triphylla, a species from the Canary Islands sometimes 

 called "Balm of Gilead"). Labiatse. Herbs or shrubs, 

 sometimes planted in borders in the middle and south- 

 ern parts of the United States. 



Four species allied to Dracocephalum, to which the 

 first 2 belong according to Bentham. Engler and Prantl 

 consider the genus monotypic, containing only the third 

 species below. The 2 native kinds described below are 

 compact, free-flowering border perennials, with aromatic 

 Ivs. and numerous showy purplish pink fls. with blue 

 stamens, and borne in dense whorls on long racemes or 

 spikes: calyx a trifle oblique, 5-toothed; corolla-tube 

 exserted, the limb 2-lipped; stamens 4, the anthers 

 2-celled. They are not quite hardy N., and should 

 have a sheltered sunny position, or some winter pro- 

 tection. The first 2 prop, by division of the root, the 

 last by cuttings. 



cana, Hook. Height 2)^-3 ft.: sts. hard, square, 

 subshrubby: branches numerous, especially at the base, 

 opposite, hoary with a minute pubescence: upper Ivs. 



small, y<i-\y?. in. long, 

 entire, hoary, numerous 

 near the fls., ovate; lower 

 Ivs. larger, cordate- 

 ovate, dentate - serrate : 

 spikes numerous; whorls 

 dense, 15- or more-fld.; 

 corolla r in. long, limb 

 5-cleft, the lowest lobe 

 largest, crenate, revo- 

 lute. June-Oct. Mex.

mexicana,Benth. (Gar- 

 doquia betonicoldes, 

 Lindl.). Height 1-3 ft.: 

 root creeping: Ivs. \Y^~ 

 1% m - long, ovate-lan- 

 ceolate (the lower ones 

 cordate) , crenate - den- 

 tate, becoming purplish 

 below, petioled: fls. very 

 like the above, bright 

 pink. Mex., Mts. S. 

 Ariz. B.M. 3860. Rarer 

 in cult, than above; Ivs. 

 larger, longer and fewer. 

 Intro, into cult, in 1839.
